Furnace for smelting metal charge

The utility model provides a furnace for smelting metal furnace charge. The furnace comprises a furnace main body; a total oxygen burner which is provided on at least one side of the furnace main body; the control system comprises a flow valve group, a sensor and a central processing unit; the control system is set to carry out the following control: after the metal furnace charge is fed into the furnace, an oxidizing agent and fuel are fed into the furnace according to an oxygen-fuel ratio not less than 3, and combustibles in the metal furnace charge are combusted for a period of time until the metal furnace charge is preliminarily softened; and then, an oxidizing agent and a fuel are supplied into the furnace at an oxygen-fuel ratio of 1.7-2.5 and combusted to heat the metal charge. 本实用新型提供了用于熔炼金属炉料的炉，包括：炉主体；全氧燃烧器，所述全氧燃烧器被设置于所述炉主体的至少一侧；以及控制系统，所述控制系统包括：流量阀组、传感器以及中央处理器；所述控制系统被设置为进行以下控制：在将所述金属炉料送入所述炉中后，以不小于3的氧燃比向所述炉内供入氧化剂和燃料并使所述金属炉料中的可燃物燃烧一段时间直至所述金属炉料初步软化；以及然后，以1.7-2.5的氧燃比向所述炉内供入氧化剂和燃料并燃烧，以加热所述金属炉料。
